As Jeff pointed out already communities get stricter, and because of the wide audience SU is especially strict.
Since this particular question was closed solely by the community and not by a diamond moderator, I am not convinced going against the community is a good idea.
As for listing older questions that have not been closed, understand that policies change and we do not always retroactively apply changes. Some questions where posted early on, and never made the home page again, and therefore remain open. When they are highlighted, like in this question, they suddenly generate interest again, and we start a new circle of closing wars.
